lMPRCVEMENT IN FIRE-PROCF BUILDINGS.

Specification forming part of Letters Patent No. 143,197, datedSeptember 23,1873 application filed August 28, 1873.

CASE B.-

To all whom it may concern:

Be it known that I, LUoInN A. TARTIERE, of the city, county, and Stateof New York, have invented a new and useful Improvement in Fire-ProofBuildings; and I do hereby declare the following to be a full, clear,and exact description th ereof, which will enable those skilled in theart to make and use the same, reference being had to the accompanyingdrawin g forming part of this specification, in which drawinga Figure 1represents a section of my invention in a direction transversely to thefloorbeams. Fig. 2 is a similar section in a direction parallel to thefloor-beams. Fig. 3 is a perspective view of a modification of the same.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of spikes provided withsupporting hooks or heads, and intended to be fastened in woodenfloor-beams, or in strips nailed to said beams, in combination withangle-shaped brackets or bars, which are supported by said spikes, andwhich form the abutments for the filling bricks 'or tiles, in such amanner that the filling bricks or tiles protect the floor-beamseffectually against fire, and a ceiling is produced which is fire-proof,cheap, light, and durable.

In the drawing, the letter A designates a spike or screw, which isprovided with a head, a, and which is fastened either directly in one ofthe wooden floor-beams B, or in strips D of wood, which are nailed tosaid floor-beams. Each of the spikes supports a bracket, 0, of metal,said brackets being made by preference angle-shaped, as shown, anddetached one from the other. If desired, however, an-

gle-shaped bars 0* may be employed, each of which is supported by anumber of spikes or screws, A. The spikes A, instead of being made withheads a, may be constructed with supporting-hooks a (see Fig. 3,)and inthis case the bars or brackets 0* are simply placed upon the said hooksafter the spikes have been secured in position in the floor-beams, or inthe timbers attached to said floor-beams. The brackets G or bars (3serve to support the fillin g bricks or tiles E, which restlooselythereon, so that they are not liable to be afiectedby any change in theposition of the brackets or bars, and the spaces between the fillingbricks or tiles are filled up by cement or other suitable material.

By these means the filling bricks or tiles form a protection for thefloor-beams against fire, and the security of the'building is materiallyincreased.

My ceiling can be readily put up in any building, and it can be madewith any desired finish.

What I claim as new, and desire to secure by Letters Patent, is-

The spikes A, provided with supporting hooks or heads, and intended tobe fastened in wooden floor-beams B, or in strips nailed to said beams,in combination with bars or brackets O, which support the filling bricksor tiles of a ceiling, substantially in the manner shown and described.
